INERT DEACTIVATED. This is an early British WW2, 1940 dated mark 1 wood and brass drill round for the 40mm British Bofors QF 40 mm Mark I gun (40 x 311R). The gun was developed by AB Bofors of Sweden and the 40mm version was adopted by the British just prior to the start of WW2. This is an early British made drill round for the British Bofors gun. The round is made out of a turned brass base resembling the bottom of a Bofors case 1 ½ inches long and a brass top 4 ½ inches long. The wooden profile between the two brass ends appears to be ash, a hardwood. The round is weighted internally to resemble the complete round. This profile enabled the round to be fed into the action when gun drill was carried out. This drill round is headstamped 40 M/M GUN RL (Royal Laboratories) 8/40 (August 1940 date) and several other stampings. The screw in primer would have originally had a hard rubber insert to protect the firing pin during practice. The Bofors gun had a harsh action and the ammunition had to be made accordingly. This wood and brass drill round is a rare survivor from the first batch of British drill rounds, which were soon changed to made them more durable, utilising brass and steel instead of brass and wood. The price includes UK delivery and no licence is required to possess this inert round in the UK if retained as part of a collection or display. O 1775
